West Seattle traffic alerts: Spokane Street Viaduct’s next round

Thursday is when SDOT and WSDOT are usually out with construction-related traffic alerts for the next week – and for starters, we just got the plan for the Spokane Street Viaduct Widening Project, in its final weeks. Some overnight, one-direction closures are coming up – read on for the full list:

All eastbound travel lanes on the Spokane Street Viaduct will be closed at First Avenue S overnight Friday, August 3, from 10 p.m. until 5 a.m. on the following morning. During the closure, all eastbound traffic will exit at the First Avenue S off-ramp. Motorists wishing to access the I-5 or Columbian Way on-ramps can continue eastbound on the lower/surface S Spokane Street to Sixth Avenue S, where they can connect to the ramps.

The westbound travel lanes of the Spokane Street Viaduct between I-5 and SR 99 will be closed for two nights the following week, Monday, August 6, and Tuesday, August 7, from 10 p.m. both nights until 5 a.m. the following mornings.

Calendar of Upcoming Project Traffic Impacts:

Thursday, July 26 – Friday, July 27

· Southbound traffic on E Marginal Way S will jog to the west at S Spokane Street before returning to E Marginal Way S both nights form 10 p.m. until 5 a.m. the following morning.

Monday, July 30 – Thursday, August 2

· The eastbound First Avenue S off-ramp will be closed for four consecutive nights from 10 p.m. each night until 5 a.m. the following morning. The Fourth Avenue S off-ramp will remain open.

Friday, August 3

· The eastbound travel lanes of the Spokane Street Viaduct will be closed at First Avenue S overnight from 10 p.m. until 5 a.m. Saturday morning. During the closure, all eastbound traffic will exit at the First Avenue S off-ramp.

Tuesday, August 7

Southbound travel on First Avenue S will be closed overnight from S Horton Street to S Spokane Street from 10 p.m. until 5 a.m. on Wednesday morning. Southbound traffic will be detoured to Fourth Avenue S at S Horton Street.

4:41 PM UPDATE: In comments, David pointed out that if WSDOT went ahead with its “close the southbound Alaskan Way Viaduct Sun-Thurs nights TFN” plan on August 6th and 7th, it could be even worse trouble for late-night drivers .. but it DOES appear, per this even-newer advisory, that the state will NOT close the southbound AWV/99 those nights – see here. (We will put together the usual “all closures day by day” mashup a bit later.)

David – I’m looking at a SEPARATE advisory that just came in (the weekly construction lookahead) and it looks like that will indeed be the case. I’m going to have to put these all together in one lineup ahead a little bit later, so watch for that … this is per SDOT, not WSDOT, which said the Sun-Thurs pattern would continue TFN, but usually SDOT is the first to publish it …

SDOT and WSDOT work very closely together to ensure that the westbound lanes of the Spokane Street Viaduct never close on the same nights that southbound SR 99 closes. We realize this would make getting back to West Seattle very difficult and will not let the two closures happen on the same nights.
